Product details
Overview
JANS1N4113-1/TR from Microsemi is a 500 mW, 19.0 V Zener voltage regulator diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435, with 1% voltage tolerance, 150 Ω dynamic impedance at 250 mA, and max reverse leakage of 0.05 µA at 15.2 V. It serves as a precision reference in radiation-hardened military power supplies.
For engineers reviewing the JANS1N4113-1/TR datasheet, JANS1N4113-1/TR pinout, JANS1N4113-1/TR application, or JANS1N4113-1/TR equivalent, key selection criteria include Zener voltage stability over temperature (αVZ = +0.090 %/°C), low noise density (1 µV/√Hz), hermetic DO-35 packaging, and JANS-level reliability for high-reliability aerospace systems.
Technical Context
This device operates in reverse breakdown to maintain stable 19.0 V regulation across 250 mA test current and supports full-rated power dissipation up to +50 °C before linear derating to zero at +175 °C. Its metallurgically bonded junction ensures low thermal resistance (RθJL = 250 °C/W) and inherent radiation hardness per Microsemi MicroNote 050.
The cathode band identifies polarity for proper orientation in series-shunt regulation circuits; it exhibits minimal capacitance (~3 pF typical at 19 V) and ESD insensitivity per MIL-STD-750 Method 1020, making it suitable for low-noise analog references in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 19.0 V ±1% at 250 mA - enables precise voltage reference in regulated power rails |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous operation in compact axial-leaded layouts |
| Dynamic Impedance ZZT | 150 Ω @ IZT = 250 mA - ensures tight regulation under load transients |

| Noise Density | 1 µV/√Hz - critical for low-noise instrumentation and ADC reference applications |
| Temp Coefficient αVZ | +0.090 %/°C - predictable drift behavior simplifies temperature compensation design |
| Junction Temp Range | –65 to +175 °C - validated for extended-range operation in space and defense platforms |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with hermetically sealed body, tin-lead or RoHS-compliant matte-tin plating, and cathode identified by a single black band. Weight ≈ 0.2 g; lead length 25.4–38.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node in Zener regulation; must be negative relative to cathode during operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4113-1 | Same 19.0 V, 1% tolerance, DO-35 package, but qualified only to JANTXV level (not JANS); lower screening rigor and no Class S radiation testing | Suitable for ground-based military systems where full space qualification is not mandated | Select JANTXV1N4113-1 when cost sensitivity outweighs need for radiation hardness and extended temperature screening |
| 1N4113US-1 | Same electrical specs and DO-35 package, but commercial-grade (non-mil) with RoHS-compliant matte-tin plating only; no MIL-PRF-19500 qualification | Applicable in industrial test equipment or non-safety-critical embedded systems with benign environments | Choose 1N4113US-1 for prototyping or volume production where mil-spec documentation and traceability are unnecessary |
Compared with JANS1N4113-1/TR, JANTXV1N4113-1 offers reduced cost and faster lead times but lacks radiation hardness validation and Class S screening, while 1N4113US-1 sacrifices all military qualifications for RoHS compliance and commercial pricing-neither is a drop-in replacement for JANS-level mission assurance requirements.

FAQ
What is the Zener voltage tolerance of JANS1N4113-1/TR?
JANS1N4113-1/TR has a nominal Zener voltage of 19.0 V with ±1% tolerance, verified at 250 mA test current and 25 °C ambient. This tight tolerance is achieved through post-trim screening and is maintained across its qualified temperature range of –65 to +175 °C, making JANS1N4113-1/TR suitable for applications demanding high initial accuracy without calibration.
Is JANS1N4113-1/TR compatible with lead-free soldering processes?
JANS1N4113-1/TR uses standard tin-lead plating and is rated for soldering at 260 °C for 10 seconds per MIL-STD-750 Method 2026. While not RoHS-compliant due to its JANS qualification, it can be processed using lead-free reflow profiles with appropriate thermal profiling-but Microsemi does not guarantee performance or reliability under Pb-free assembly without validation per customer-specific process qualification.
What is the maximum reverse leakage current for JANS1N4113-1/TR?
The maximum reverse leakage current for JANS1N4113-1/TR is 0.05 µA measured at 15.2 V (80% of VZ) and 25 °C. This ultra-low leakage supports ultra-low-power standby modes in battery-operated systems and reduces error contributions in high-impedance reference circuits where JANS1N4113-1/TR is used as a precision shunt element.
Does JANS1N4113-1/TR require heatsinking in normal operation?
No, JANS1N4113-1/TR does not require external heatsinking when operated within its 500 mW power limit and with leads trimmed to 10 mm from the package body (RθJL = 250 °C/W). At 250 mA and 19 V, power dissipation is 4.75 W - far exceeding rating - so JANS1N4113-1/TR must be used at currents well below IZM = 14.5 mA to stay within safe thermal limits.
How is polarity marked on JANS1N4113-1/TR?
JANS1N4113-1/TR uses a single black cathode band on the glass body to indicate the cathode terminal. The banded end must be connected to the higher-potential node for proper Zener regulation; applying forward bias (anode positive) results in ~1.1 V drop but risks exceeding forward current limits if uncontrolled. Polarity marking complies with JEDEC DO-35 mechanical standards and is visible under standard visual inspection.
